  1. Hello, I'm working on a program that save multiple values in a data table and at the same time in a CSV file every 200ms. Every thing is fine when I look at my data table in Unilogic, every value is saved there every 200ms but for some reason, on the CSV file, the data from row 0 to the current row is appended again every 8 seconds or so. I can add my program if anyone can look at it. Thank you
  2. Hello I am fairly new in UniStream and still can't find my footing. What I want to do is to store file first into CSV on SD, then to UDTF and later to read the UDTF file on a Data Table. But, when i try to convert the CSV into UDTF I keep getting "-4" as status. I tried this function on the example for Data Table, with me first making a csv file with "Store DTI to File", next trying to convert the made file into UDTF, but the end status is "-4". I have read the CSV file on the computer, and it has what the original UDTF table has, so that should not be the problem. Is there something I am doing wrongly? It would be great if someone could advise me on this. Also, after rereading many times the help file, I have this question: why can't one write '0' for "Parameter E"? I agree, that if one converts the csv from a created file with "Store DTI to File", one should for sure delete the first column, so that the table could read the new UDTF. But what about if one makes a CSV file like the one in the "Log to File" example in the "UserLogs" folder? I have attached the added rungs on the "Indexed Data Table" example I made. I am using USP-156-B10. On the example HMI, I have added 2 buttons: 1st for Storing as CSV, 2nd for converting CSV into UDTF.
  3. What the main goal is: To download a CSV file from an external source and then transfer that data into an array which will be used throughout the program. I assumed my first step was to convert a CSV file to a udtf file and then use the function "Copy column to array". However, when I try and use the CSV to UDTF my status bar always shows "-1", I have a micro SD card in the slot and a USB in another slot with the required CSV file. I also tried just putting the file onto the micro sd card but that also didn't seem to work... Am I using the function properly? Any advice would be helpful as this is my first time using Unitronics Thank you
  4. I have a bunch of USMP files (trend data). Not all have ended up as zipped CSV files. What format are the USMP files? Looks like XML in the header, but I can't crack the encoding used for the actual data. Is there a file converter available for USMP files?
  5. Why does the "Store to DTI File" function create multiple files when I set "F" Parameter to #1 (Create CSV file). I expected just a CSV file, but it created a "*.UDTF", "*.CSV", and a "*.CSV.ZIP" on the SD card too? I would prefer the program only to save the DT to "*.CSV file". DTI Infolog Sub.pdf
